PostHog shares engineering principles for building agent-first products, emphasizing agents as a primary interaction layer with full feature parity to humans, not bolt-on features. After two architecture overhauls, their MCP now serves 6K+ daily active agents. Key lessons include semantic abstraction (SQL over endpoints), context optimization, and encoding domain knowledge in agent skills.
